Formally Double Bonded

Hydroxyl Compounds, Donor-Acceptor Oxides, and Oxyacids

This page under construction, but many of the calculations are done!

This catagory includes HNO3 and H2CO3 and other hydroxyl-oxides that require a double bond to achieve a Lewis octet. Please see Hydroxyl Compounds, Donor-Acceptor Oxides, Oxyacids, and Anions for other similar compounds, including H2SO4 and H3PO4.

Hydrates

The hydrates of these compounds are the point of intersection with the Hydroxyl Compounds, Donor-Acceptor Oxides, Oxyacids, and Anions. For example, the hydrate of formaldehyde is "dihydroxylmethane," and the hydrate of HPO2[i.e. O=PH->O] is H3PO3 (phosphorus acid)."
